3 Types of Skin Cancer

Is melanoma no big deal?

Melanoma is the most invasive skin cancer with the highest risk of death. While it's a serious skin cancer, it's highly curable if caught early. Prevention and early treatment are critical, especially if you have fair skin, blonde or red hair and blue eyes.

There are around 16,700 new melanoma skin cancer cases in the UK every year, that's 46 every day (2016-2018). Melanoma skin cancer is the 5th most common cancer in the UK, accounting for 4% of all new cancer cases (2016-2018).

What is the average age for melanoma?

[1-4] In contrast to most cancer types, melanoma skin cancer also occurs relatively frequently at younger ages. Age-specific incidence rates increase steadily from around age 20-24 and more steeply in males from around age 55-59. The highest rates are in in the 85 to 89 age group for females and males.

Can a melanoma be benign?

Melanoma, benign: A benign growth of the melanocytes that is not cancerous. A mole may be a melanocytic nevus.

What is the timeline for melanoma?

Melanoma can grow very quickly. It can become life-threatening in as little as 6 weeks and, if untreated, it can spread to other parts of the body. Melanoma can appear on skin not normally exposed to the sun. Nodular melanoma is a highly dangerous form of melanoma that looks different from common melanomas.

What are the odds my mole is melanoma?

The rate is similar between men and women younger than 40 years but becomes substantially higher for men older than 40 years. For a 20-year-old individual, the lifetime risk of any selected mole transforming into melanoma by age 80 years is approximately 0.03% (1 in 3164) for men and 0.009% (1 in 10 800) for women.

What is the strongest risk factor for melanoma?

Ultraviolet (UV) light exposure

Exposure to ultraviolet (UV) rays is a major risk factor for most melanomas. Sunlight is the main source of UV rays. Tanning beds and sun lamps are also sources of UV rays.

What happens if a skin biopsy is positive?

Generally, after a patient receives positive melanoma results, his or her doctors will need to proceed with staging the malignancy— which essentially means determining the extent of the cancer—and developing a treatment plan based on how far the cancer has progressed.

What's the survival rate of melanoma?

Five-Year Survival Rate by Melanoma Stage:

Localized melanoma: Stage 0, Stage I, and Stage II: 98.4% Regional melanoma: Stage III: 63.6% Metastatic melanoma: Stage IV: 22.5%

Why is melanoma more common now?

As we age, our bodies' ability to fight mutation decreases, while DNA damage increases, leading to higher melanoma rates among aging populations. At the same time, life expectancy rises globally, leading to a larger aging population and thus more incidences of skin cancer and melanoma.

Can you have melanoma for 3 years and not know?

“You could have melanoma for a long time before you realize it, because some types are not so obvious. Some aggressive forms, like nodular melanoma, grow fast, are visible and can hurt or bleed.” While certain groups may be at a higher risk for melanoma, anyone can get the disease.

What are the early warning signs of malignant melanoma?

Spread of pigment from the border of a spot into surrounding skin. Redness or a new swelling beyond the border of the mole. Change in sensation, such as itchiness, tenderness, or pain. Change in the surface of a mole – scaliness, oozing, bleeding, or the appearance of a lump or bump.

How quickly should melanoma be removed?

Hypothesis-based, informal guidelines recommend treatment within 4–6 weeks. In this study, median surgical intervals varied significantly between clinics and departments, but nearly all were within a 6-week frame. Key words: melanoma, surgical interval, treatment time, melanoma survival, time factors.

What organs does melanoma spread to first?

Doctors have known for decades that melanoma and many other cancer types tend to spread first into nearby lymph nodes before entering the blood and traveling to distant parts of the body.

Can you live to 80 with melanoma?

For people with "thin melanoma," defined as being less than 1 millimeter in maximal thickness, that has not spread to lymph nodes or other distant sites, the 5-year survival is 99%. However, for people with thicker melanoma, the 5-year survival may be 80% or higher.

When is melanoma too late?

What are the signs of late-stage skin cancer? Melanoma is considered stage 4 when it has metastasized to lymph nodes in a part of the body far from the original tumor or if it has metastasized to internal organs like the lungs, liver, brain, bone or gastrointestinal tract.

What is the number one cause of melanoma?

Still, doctors believe exposure to ultraviolet (UV) radiation from the sun and from tanning lamps and beds is the leading cause of melanoma. UV light doesn't cause all melanomas, especially those that occur in places on your body that don't receive exposure to sunlight.

Where is the most common place to get melanoma?

In men, melanoma is most commonly found on the back and other places on the trunk (from the shoulders to the hips) or the head and neck. The most common sites in women are the arms and the legs.

Is melanoma usually caught early?

Melanoma can often be found early, when it is most likely to be cured. Some people have a higher risk of getting melanoma than others, but it's important to know that anyone can get melanoma.
